memora: Version-Controlled, Typed Memory for AI Agents – Git for AI Beliefs

memora is a CLI tool that version-controls AI agent memory—typed, provenance-tracked, branchable, mergeable. Think git for what the AI believes about your codebase, not file changes. The entire project is ~5k lines of Rust across two crates, producing a single static binary with zero external dependencies (SQLite bundled via rusqlite). Runs on all three major platforms with CI.

Crate Structure

• memora-core – library with no CLI deps. Types, SQLite store, snapshot engine, 3-way merge, session recording, export adapters.
• memora-cli – thin clap-based CLI layer on top.

Technical Highlights

• Clock trait for deterministic tests – no flaky timestamps.
• Content-addressed IDs via SHA-256 of canonical form strings.
• Three-way merge with BFS merge-base detection across the full parent DAG.
• node_versions table that snapshots full node state per commit – enabling diff, rollback, and reversible GC.

Design Decisions & Open Questions

The author is seeking feedback on several areas:

• Importance scoring formula for GC and export ranking.
• Whether the MemorySource enum should be open (currently has an Unknown(String) variant).
• Remote sync model – currently filesystem-only; the copy_commits_between boundary is where network transport would plug in.
